Each program’s content is enhanced by geologic maps, photos, and Google Earth imagery. Session Information Grand Canyon, Arizona A mile-thick package of sedimentary rocks from the Paleozoic Era is spectacularly exposed from the Grand Canyon’s rim to bottom. Each layer has a story to tell, revealing ancient oceans, rivers, and sand dunes that reflect drastically changing environments through geologic time. Kempter explores and interprets ancient Precambrian rocks now exposed in the inner gorge, along with a boundary known as the Great Unconformity, where more than a billion years of rock information is missing. When and how did the Colorado River carve the Grand Canyon? These questions, which are still being debated by geologists, are addressed in the program.
